WILLIAM W. DEAN, OF ELYRIA, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THEGABFORD MANUFACTURING COMPANY, OF ELYRIA, OHIO, A CORPORATION OF OHIO.

TELEPHONY.

Application filed August 6, 1909.

To all whom it may concern Be it known that I, WILLIAM W. DEAN, acitizen of the United States, residing at Elyria, in the county ofLorain and State of Ohio, have invented certain new and usefulImprovements in Telephony; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

I My invention relates more particularly to telephone casingsiandespecially to telephone desk sets and the details thereof.

Some of the objects of my invention are to provide a desk set, all ofthe parts of which are rigidly connected to one another, thus avoidingthe use of unnecessary pivot connections between the various frameparts; to provide a convenient arrangement for associating the switchhook and the contacts controlled thereby with the casing in such a waythat they are accessible to the workmen; to provide connections betweenthe various parts of the casing in such a way that they do not interferewith the cleaning of the exterior of the casing,'and

. at the same time those-which are operable may be accessible from theexterior of the casing. I have endeavored to produce such a desk set byconnecting the various casing parts and to reduce the number of theseparts to as few as possible, making a cheap, compact and easilyconstructed set.

In desk stands now in use, the transmitter and mouthpiece are pivoted tothe standard. In eliminating this I construct my desk stand so that thefront of the transmitter is inclined at an acute angle to the vertical;that is, a line drawn through the face of the front to intersect a linedrawn through the axis of the standard, intersects the same, making theangle nearest the instrument less than a right angle. I have so inclinedthis front for the purpose of making the mouthpiece convenient to onewho seated at a desk, uses the telephone. Of course the inclination ofthe front may be changed to suit different conditions and for differentpositions of use. For the general use to which desk sets are placed theyare either set on a desk and talked to or held in the hand. In theformer case, the stand setting on the desk presents the mouthpiecebelow, the mouth of the user; in the latter, the user Specification ofLetters Patent.

holds the stand so as to receive some support therefor from the chair orhis body in In the drawing, Figure 1 is a cross-section.

through the desk set showing the arrangement for supporting thetelephone apparatus therein and the connection between the various partsof the casing. Figs. 2, 3, 4:, 5, and 6 are details of the casingshowing the means for connecting the detachable parts to the casingproper.

l is the hollow base to which the vertical standard portion 2 isattached. In the drawing these parts are shown as drawnfrom the samepiece of metal.

3 is an enlarged hollow casing adapted to house part of the telephoneapparatus attached to the upper part of the tubular casing. The parts asshown in the drawing are united so as to form a single compartment forthe apparatus, each part communicating with the others, either directlyor through the hollow standard. By eliminating partitions I lighten theset and facilitate the running and making of the circuit connections. Inthe form shown inthe drawing the standard 2 is extended into a narrowfinger piece 17, and the enlarged casing 3 attached thereto by thescrews or rivets 18 which make a rigid connection between these parts. Ahollow portion projects frointhe hollow casing and, in the form shown,telescopes with the standard, being rigidly connected therewith, Thefront of the enlarged. casing is inclined at an angle to the standard 2,and a front piece 4 carrying the mouthpiece 5 is adapted to bedetachably connected theretoto close the front of this casing. Aninverted cup 6 is fastened in the base of the set. A cover 7is adaptedto be detachably connected to close the mouth of the cup 6. An annularangular ring 14 is shown bent over the edge of the cup. An annularrubber ring 8 is inclosed between the lower desk set.

edge of the base and the set and this angular ring, furnishing aresilient bufier for the p The bottom 7 ofthe cup is fastened thereto bya hook 35 which fits over the angular ring as shown in the drawing,

and a rotatable catch member 13 which engages the annular ring 14 as acounterpart or cotiperating catch member when the memof the catch 13 toengaging position with the counterpart catch member on one side and tocomplete disengaging position with the said catch member on the otherside.

"A screwdriver or similar tool may be in- .3 L'ing, are arranged to hookover each other casing.

casing portion is connected thereto by a "joint and catch arrangementvery similar to that just described. A catchhook 46 and serted throughthe recess 12 into the slot 11 to rotate the member 13 in order to lockor 25 release the bottom to or from the cup. The

terminals 15 are'mounted in the base of the casing and the conductors 16extended through the standard portion to the contacts which are includedin the enlarged hollow The front of the enlarged upper a counterpartcatch member 45, the former attached to the front, the latter to theeaswhen the front is placed upon the casing.

At 19 I show a catch housing attached by rivets 32 to the enlarged uppercasing portion. A hook catch member 21 is inclosed within this casing torotate between abutments 38 and 39 formed on the casing 19 and whichlimit the rotation of the hook. "hook catch 21 is bent upward at andextendedinto a hook 30. A slot 22 is cut in The the base of the hookcatch and coeperates with the recess 20 in the casing 3. The hookengages with acounterpart catch member 31 I formed on the front piece.In the drawing this piece is shown in the form of a tongue out from thefront itself and bent upward. Aftool maybe inserted through the recess20 into the slot 21 and the hook rotated between the limits oftheabutments which confine the movement-from full engagement positionbetween the catch members and position of complete disengagement.

It will beseen that I thus provide means for conne'cting thesedetachable parts which are located entirely within the casing and whichmay be operated to quickly and easily unlock the catches by meansinserted from 7 without the casing.

The transmitter bridge bearing a trans- ]mitter and attached to thecasing front is.

I bracket.

shown at 23. I show a bracket 40 attached at 24 to the standard portionand extending upward into the enlarged part of the casing. The switchhook 43 is pivoted at 42 to said The contacts 25 and 41 and a hookcontrolling spring 44 are also carried by this bracket. The switch hook43 controls the connection and disconnection of the springs 25 and 41.The contact springs and the switch hook arrangement and other apparatuscarried by the bracket, can be easily reached by removing the front 4.

I thus provide a desk set which is simple, and compact. The telephoneapparatus is inclosed in the two extremes of the set and the portions ineach extreme may be readily reached by removing the detachable portionsat the top and bottom of the casing. These detachable portions are notattached by any complicated locking mechanism, and yet this lockingmechanism is of such nature that it cannot be operated without the useof some tool. It is simple of construction and easy to operate, so thatthe apparatus inclosed within the casing can be quickly and easilyapproached.

While I have shown and described this particular form of my inventionwhich is my preferred form, it will be obvious to those skilled in theart that numerous and extensive departures from the'form and details ofthe apparatus thus shown, may be made without departing from the spiritof this invention, the same being herein shown solely for the purpose ofclearly illustrating one specific embodiment thereof.
